Hello Everybody

I hope some of you may recognize in this forum as a Happy BSNL Broadband user from Bangalore.

But not any more.

Since around 1 month, the connectivity is badly unstable.
The lack stability in the connectivity is very irregular.
We are living in an apartment and line man from BSNL checked the phone line twice.
He even replaced the wires joining the concealed wires for our apartment.
He closed the complaint himself by suggesting to check the concealed wires with an electrician.
I don't expect any issues in the concealed wiring, even if, the lack of stability should be consistent.

I have a Teracomm Type 2 router.

Here is the overview.

ATTN is high. Just un check ADSL2+ button. Save reboot and recheckSNR Attn values.
 
Please also confirm problem solved or not. Whether connection stability improved.SNR expected to improve at least by 2 dB or 3 dB.
 
which attenuation level should be check for line quality , is it local attenuation or remote line attenuation.

my data shows, pls suggest if it is best?

Check Remote SNR/ ( download ) Local SNR (upload ) ( above 10 dB)Attn usually remains same. Acceptable. values now. ( Below 30 dB preferred)
 

Just for testing, try installing the modem at the phone outlet that is closest to the pair box, and check.
 
thanks essbebe and x760 for your quick reports, I didn't get email notifications of your replies.just now checked.I will now try disable Adsl2+ and let you know the results.
 
I have now disabled adsl2+.attn at this time was 56 and now it is 54 now.and in snr the biggest improvement observed.I am getting 9.24 as snr downstream values. I didnt get 9+ snr values for downstream at any point of time recently.since yesterday night, the connection became as stable somehow.but I expect the problems in peek hours, so I'll observe the results at the time and let you all know.
 
These values are still very bad, if you install the modem closest to the pair box, you can be certain of the concealed wire to a certain extent.
 
My connection speed and stability purely appears to be time bound.
My connection appeared to became stable since last night but it lasted only till today morning.
Now ADSL link disconnects every 5 minutes.
I was always getting 3+MBps since last night even in foreign servers such as Kuwait till today morning.
Now i am hardly getting 1MBps even in Chennai Servers.

Here is the current reading.

Pleases suggest the course of action i can take, i am clueless as of now.

----------

My JTO is refusing to accept the problem i am experiencing to be a BSNL Network issue.
But, i think it cannot be a phone line issue either, if it is, how can the connectivity become unstable in day time only
 
From what I can gather some of the BSNL gateways have issues with them (insanely high latency), though I doubt that would affect snr values. For example, even when I'm connected to a faulty gateway my downstream SNR remains constant at 30.3 dB and attenuation at 1.8 dB. You could try emailing the NOC or complaining to your SSA's GM, both will result in some quick action.

O/o DGM ( Broadband,Multiplay,Admin),Bangalore - http://www.datanetwork.bsnl.co.in/aboutus.htm

What were your snr values before the issues started ?

Someone from BSNL just paid a visit, there is some issue at the NOC, he said they've forwarded the complaint, should get resolved today.

On my 2mbps plan 😛
 
I am not sure what magic has happened since the email i sent to NOC and GM Broadband yesterday night.
As of now, the ADSL link has not dropped even once so far.
Speeds are rocking at 3+ MBps.
Latency is very very low.
Fingers crossed.

Still the latency and snr are bad.
So, there isn't any relation to the connection quality between these technical parameters?

----------

One more crucial thing to note is.
Today power has not been cut even once.
If our apartment's generator provides the power, my router doesn't like that.
It would destabilize the ADSL Link.

Please share your ideas on possible solution for this problem.
